HOSE-COUPLING.

Specification of Iietters Patent.

Patented June 30, 1914.

To all whom it may concern:

Be it known that I, JOHN GE'rHINe, a citizen of the United States, residing at Youngstown, in .the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification. A

My invention relates to hose couplings and the clamps forming part of such devices, used in securing the coupling members in place on the end of asection or length of hose formed of rubber, woven fabric or other suitable flexible material.

- One object of my invention is to provide a hose coupling of improved construction having novel means whereby the hose coupling members are fastened and held in position on the ends of the hose'sections.

Another object of my invention is to provide a hose coupling having improved means whereby the hose clamping members of the coupling are tightened and held in position on the hose in securing the end of the hose in place on the coupling, which,

- together with other objects of this invention will be more clearly understood as the invention is more fully described hereinafter.

Referring to the accompanying drawings forming part of this specification, Figure 1 is a longitud'nal plan showing one section of a hose coupling, constructed and arranged in accordance with my invention, as attached for use tothe end of a flexible hose. Fig. 2 is a longitudinal section of the same showing the coupling member as "inserted within the end of the hose, the section being taken on the line 11-11 of Fig. 3. Fig. 3 is an end elevation of the construction illustrated in Figs. 1 and 2. Fig. 4 is a transverse section taken on the line -IV-IV of Fig. 1. Fig. 5 is a lan showing a development of the clamp orming part of this invention and illustrated in Figs. 1, 2, 3 and a. Fig. 6 is a longitudinal plan similar to that shown in Fig. 1 showing a modified form of clamping member as made in accordance with my lnvention. Fig. 7 is a longitudinal sectional plan of the apparatus shown in Fig. 6, the section being taken on the line VIIVII of Fig. 6. Fig. 8 is an end elevation of the construction illustrated in Figs. 6 and 7. Fig. 9 is a sectional end elevation of the same,

the, section being Application filed January 11, 1912. Serial No. 670,626.

takenon the line IXIXof Fig. 6. Fig.

10 is a development of the clamp employed inthe construction shown in Figs. 6, 7, 8 and 9.

In the drawings, referring to Figs. 1 to 5, the numeral 2 designates one end of. a section orlength of a flexible hose to which my improved hose coupling and the clamp forming part thereof are applied for use. The hose maybe formed of rubber, canvas, or other fabric, a rubber coated fabric, or other suitable'material. A hollow tubular metal sleeve or nipple 3 having its outer end provided with screw threads i is inserted within the hose 2, this nipple preferably being formed of or from a short piece of metal pipe or tube, the portion thereof within the hose having a smooth outer surface practically free from projections. On the outside of the end of the hose 2 and tightly held in engagement with the outer surface thereof 'is-a clamp 5 forming a novel part of this invention. As will be best seen in the development shown in Fig. 5 the clamp is formed of a thin flat rolled metal sheet or plate which is sheared and punched to the contour shown in Fig. 5 and is then bent into the. shape shown in Figs. 1 to 4. By reference to Fig. 5 it will be seen that the circular portion 6 of the sheared and punched late has an aperture or hole 7 therein 0 substantially the. diameter of the nipple or sleeve 3, the outer threaded end 4 of this nipple extending through this opening when the parts are assembled in securing the hose 2 to the coupling of which the nipple 4 or its equivalent forms a part.

Projecting outwardly on opposite sides of the axial center of the circular central portion 6 of the clamp are prongs 8 and 9 and extending outwardly on opposite sides of the axial center of the central portion 6 and at right angles to the prongs 8 and 9 are similar prongs 10 and 11. The prongs have pointed outer ends 8*, 9 10 and 11, and the opposite extending prongs 8 and 9 are of about the same'length. The oppositely extending rongs 10 and 11 are of about the same lengt the prongs 8 and 9 being somewhat shorter than the prongs 10 and 11. Extending outwardly from opposite side edges of the prong Sadjacent to its pointed outer end are the tongues 12 and 13 and exthe prongs and in this positely projecting tongues 14 and 15. The outer ends of the tongues 12 and 13, 14 and 15 have openings or holes 12*, 13, 14, 15 therein for a purpose described later.

After the clamp has been formed as shown in Fig. 5, the prongs 8, 9, 10 and 11 are bent at an intermediate "point in their length, closely adjacent to the inner ends thereof so as to bring the bent outer ends of the prongs into planes substantially perpendicular to the plane of the central portion 6 or in other words cause the prongs to extend substantially parallel to the longitudinal center of the nipple 3. The distance from the center of the opening 7 to the corners formed by bending the prongs will vary to suit the diameter of the hose to which the clamp is applied. The pointed ends 8 9 10, 11 of the prongs are bent inwardly slightly beyond the plane of the inner surface of the prong of which they form a part as will be seen by reference to Figs. 1 and 2. After the prongs have been bent in this manner the tongues or wings 12 and 13 are bent or curved into the cylindrical shape shown in Figs. 1, 2 and 3, the ends of these tongues being bent outwardly to form opposite lugs 16 and 17, in which the holes 12' and 13 are located, these holes then registering one with the other. A bolt 20 is then inserted in the registering openings 12 and 13 and a nut 21 screwed on the threaded end of the bolt 20. The tongues 14 and 15 on the prong 10 are then bent in a similar manner and a bolt 22 having a nut 23 isinserted in the registering holes 14 and 15 in the lugs 18 and 19 formed oni the ends of the tongues 14 and 15 in the same manner as in the tongues 12 and 13. The sleeve or nipple 3 is inserted within the end of the hose 2 and the clamp 5 is placed in position around the nipple, the sleeve projecting through the opening 7 so as to bring the circular portion 6 of the clamp 5 adjacent to or in contact with the end of the hose 2. The nut 23 on the bolt 22 is then tightened so as to draw the prongs 8 and 9 tightly into engagement with and securely hold the hose in place on the sleeve or nipple 3. The nut 21 on the bolt 20 also is tightened so as to draw up the prongs 10 and 11 in a similar manner. When the prongs 8 and 9, 10 and 11 are tightened into lace, the inwardly inclined pointed ends of these prongs will dig into the flexible material forming the hose 2 so as to add to the frictional force by which the hose is held in place on the sleeve or nipple 3 by the contacting surfaces of way increase the holding power of the clamp to a large eX- tent. means is employed in detachablysecuring the screw threaded ends of the nipples togethcr and in this way coupling the adjar cent ends of two sections of hose.

A pipe coupling 24 or equivalent,

In the construction shown in Figs. 6, 7 8, 9 and 10 the nipple or sleeve 3 is formed in the same manner as the sleeve described hereinbefore and the clamping member 5 of the coupling is formed in a very similar manner. The clamping member 5 has-a central circular portion 6 with oppositely projecting prongs 8 and 9 and oppositely projecting prongs 10 and 11 extending outwardly lengthwise at right angles to the prongs 8 and 9. The prongs in this construction are all of the same length approximately however, their outer ends 8*, 9 103 11? being pointed and'bent or inclined inwardly in the manner before described. But one of the prongs 8 in this construction 15 provided with tongues 12 and 13 extending lengthwise from the opposite side edges thereof instead of two as in the construction of Figs. 1 to 5. The prongs 8, 9, l0, 11 are bent in the same manner as has been described and the tongues 12 and 13 are bent or curved into circular shape so as to encircle the prongs 9, 10 and 11 so that when the nut 23 On the bolt 22 is tightened in the registering holes 12 13 provided in the lugs 18, 19, on the outer ends of the tongues 12 and 13 the prongs will be caused to engage with and secure the hose 2 on the nipple 3. It should be noted that the clamps with the prongs and tongues are formed integrally from a sheet of metal so that there ille no loose partsto become disarranged or The advantages of m invention will be appreciated by those skilled in the art. A simple and cheap coupling is provided having a clamping member which effectively holds the hose in position on the coupling.

Modifications in the construction and arrangement of the parts may be made without departing from my invention.

Means other than the pipe coupling shown may be used in detachably connecting the ends of the nipples. The number of prongs on the clamps and the number of tongues embracing the prongs may be varied and other changes may be made within the scope of the appended claims.
